I have about 1400 in EU4 and have about 200 now in EU5. I like the direction of 5 and what they are doing. It is not without its flaws but the biggest issue I have is with the online resources. The EU5 wiki feels empty.
I feel people often forget how long EU4 has been out on the market and how much has changed in it over the years. I think the same happens in EU5 the basis is there now and from now on it will get consistently better.
